Princess Anne made a conscious decision not to give royal titles to her children, so Peter Phillips and Zara Tindall’s spouses also have the freedom of being able to live a more normal lifestyle. Phillips married NHS nurse Harriet Sperling in June, while Zara married England rugby player Mike Tindall in 2011. The sports star might not be your typical royal, but former royal butler Grant Harrold says Mike has “done some extraordinary things” during his time in the family.

“Mike is very grounded. That's what I like about him,” Harrold says. “He’s got a great relationship with everyone, obviously Princess Anne and The King. He’s just Mike. I think they like the fact that he's a bit different.”

Princess Anne’s son-in-law is a co-host of the popular podcast “ The Good, The Bad & The Rugby ,” and has also starred on the reality show I’m a Celebrity… Get Me Out of Here!…
